VENTILATION OF STORAGE-BATTERY CELLS.

Specification of Letters Patent.

Patented Dec. 31, HHS.

Application filed February 8, 1918. Serial No. 215,986.

To all whom it may concern:

Be it known that I, BRUCE Form, a citizen of the United States, and aresident of Philadelphia. in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful improvements intheVentiof which the following is a specification,

The principal objects of the present invention are, first, to provideforinsuring proper ventila 'on of storage battery cells, moreparticularly submarine cells; and second, to provide a comparativelyinexpensive, reliable and easily manufactured fitting for the purposeabove mentioned.

The invention will be claimed at the end hereof, but will be firstdescribed in connection with the embodiments of it chosen for the sakeof illustration in the accompanying drawings forming part hereof and inwhich- Figure 1, is a top view of a cover embodying features of theinvention. r

Fig. 2, is a transverse sectional view of the same. i

Fig. 3, is a sectional view of the cover shown in Figs. 1 and 2-, withthe filling and ventilation fitting in place.

Fig. 4, is a section on the line 4--4 of Fig. 3.

Fig. 5, is a side view of the fitting detached from the cover.

- Fig. 6, is a top view of a cover showing.

the fitting in section and illustratin the application of the inventionto a di erent arrangement of accessory parts.

Fig. 7, is a vertical elevation 0i."v the device shown in Fig. 6.

Fi 8 is a section on Fig.

Fig. 9, is a view, similar to Fig. 6,-illus trating the application ofthe invention to a different arrangement of accessory parts.

Fig. 10, is a section on the line 10-l0 of Fig. 9, looking in thedirection of the arrows, and

Fig. 11, is a section on the line 11-11 of Fig. 9.

In the drawing the cover 1 is provided with a relatively large opening2. A neck 3, depends from or is arranged beneath the underface of thecover and this neck is pro .vided with ports 4 and with a fioor '5having a second and similar opening 6. The fitting is provided with aninner tube 7 closing the the line 8-8 of opening 6 and communicatingbelow the floor 5 with the space beneath the cover.

This inner tube 4 is provided with a laterui opening 8 which may beformed through a coupling 9. The fitting also comprises a shell 10, inthe form of an outer tube '11, closing the larger opening 2 andcounnunicating with the ports 1 and extending laterally to clear theopening 8. and terminating in a second lateral opening that may beprovided with a coupling -13. The fitting, with the exception of thefilling cap 14, comprises a unitary structure and can be comlparativelyinexpensively and cheaply manufactured. The .openings concentric andspaced at difierent levels and the openends of the inner and outer tubes7 and 11 of the fitting close these openings (3 and 2, and the inner andouter tubes are not in communication with each other save as they bothcommunicate with the space he neath the cover.

I have shown in the drawings. bathe-plates but theyare not claimedherein since the combination of baffle-plates with air intakes andout-takes, arranged to produce ventilation, constitutes thesubject-nutter of my application serially numbered 215,985; how ever, Imay say that in Figs. 1 to 3, the bafiie-plates 15 depend vertically andmerge into the neck 3. As shown in Figs. 6 and 7 the baffle-plate 15 isarranged parallel with the cover and projects downward from the neck 3.As shown in Figs. 9 to 11, the bafiie-plate 15 is provided with a swellor bulge 16 into which depends the end of the inner tube, and thebaffle-plate is line with the axis of the inner tube. in those figuresthe neck 3 is not provided with ports on the side thereof opposite theswell or bulge 16.

hat I claim is:

1. Improvements in ventilating storage battery cells comprising thecombination of a cover having relatively large and relatively smallconcentric openings, and a fitting provided with non-communicating innerand outer ventilating tubes of which one closes the larger opening andthe other closes the smaller opening and of which both com- 1 municatewith the space beneath the cover.

2. Improvements in ventilating storage battery cells comprising thecombination of a cover having a relatively large opening, a floor havinga smaller opening and arranged 2 and 6 are below and spaced from theunder face of the cover, a neck having ports and carrying the floor, anda fitting provided With noncommunicating inner and outer "entilatingtubes of which one closes the larger opening and communicates with theports and of which the other closes the smaller opening and communicateswith the space beneath the floor.

3. Improvements in ventilating storage battery cells comprising thecombination of a cover having a con'lparatively large opening, a neckhaving ports and depending from the cover and having a floor providedwith a second and smaller opening, and a fitting for the openingsprovided with an inner tube venting below the floor and having anoutside opening and also provided with a shell closing the-larger holeand communicating with saio ports and extending laterally to clear saidoutside opening and terminating in a second opening.

4. Improvements in ventilating storage battery cells comprising thecombination of a cover having a large opening and a second opening andcommunicating with the space.

between the cover and extending laterally to clear said outside opening.andterminating in a second opening. BRUCE FORD.
